<h2>New DAS version 1.6</h2>

<p>
The new version of DAS has many advantages to the previous 1.53E version and has been agreed upon by the DAS community as a standard:
<li>Specification is based on real world usage of DAS in the community.</li>
<li>Easy representation of more complex data using hierarchical data with the parent and parts tags in the features response, which also aids the correct diplay of features possibly with elements outside range</li>
<li>Easy searching of relevant sources from the registry as data sources provide controlled vocabulary identifiers</li>
<li>Easy access to information from a datasource as using the datasource name now brings back a sources document for that source only</li>
<li></li>

The current specification document for the new 1.6 specification can be found here <a href="http://www.ebi.ac.uk/~aj/1.6_draft5/documents/spec.html">1.6 Specification</a>.
